These renderings of the classic GMC Motor Home were created in Adobe Illustrator. It is my preferred application for creating vector graphics more efficiently. By using a vector-oriented application, files can be resized and exported in a variety of formats: PNG, PDF, TIF, SVG, JPG, etc. Illustrator art, unlike most graphics manipulated in applications like PhotoShop, is not based on bit-mapped images that can easily get pixelated when enlarged. The images you see here, however, are bit-mapped conversions.
